a controversial topic in the 2010s. Many parents and educators have been fearful of the repercussions of having social media in the classroom. There are concerns that social media tools can be misused for cyberbullying or sharing inappropriate content. As result, cell phones have been banned from some classrooms, and some schools have blocked many popular social media websites. Many schools have realized that they need to loosen restrictions, teach digital citizenship skills, and even incorporate these tools into classrooms. Some schools permit students to use smartphones or tablet computers in class, as long as the students are using these devices for academic purposes, such as doing research. Using Facebook in class allows for the integration of multimodal content such as student-created photographs and video and URLs to other texts, in a platform that many students are already familiar with. Twitter can be used to enhance communication building and critical thinking and it provides students with an informal "back channel", and extend discussion outside of class time. Censorship by governments Social media often features in political struggles to control public perception and online activity. In some countries, Internet police or secret police monitor or control citizens' use of social media. For example, in 2013 some social media was banned in Turkey after the Taksim Gezi Park protests. Both Twitter and YouTube were temporarily suspended in the country by a court's decision. A new law, passed by Turkish Parliament, has granted immunity to Telecommunications Directorate (TİB) personnel. The TİB was also given the authority to block access to specific websites without the need for a court order. Yet TİB's 2014 blocking of Twitter was ruled by the constitutional court to violate free speech. More recently, in the 2014 Thai coup d'état, the public was explicitly instructed not to 'share' or 'like' dissenting views on social media or face prison. In July of that same year, in response to WikiLeaks' release of a secret suppression order made by the Victorian Supreme Court, media lawyers were quoted in the Australian media to the effect that "anyone who tweets a link to the WikiLeaks report, posts it on Facebook, or shares it in any way online could also face charges". On 27 July 2020, in Egypt, two women were sentenced to two years of imprisonment for posting TikTok videos, which the government claims are "violating family values".
